The Even-Handed Teacher
Are teachers fair? Who knows? Are they even-handed?
That can be tested, and Lea Cohen did just that, as shown in her project display in figure below.
Figure: Project display for “The even-handed teacher.”
I believe that a right-handed teacher pays more attention to the left side of the room, so that he or she can pay attention to the class while writing on the board.
Left- and right-handed teachers
Classroom location of students called on
Fourteen classrooms, between fourth and eighth grades
Visit 14 classrooms 4 times, for 10 minutes each and observe the following:
- Whether the teacher is left- or right-handed
- The arrangement of the classroom (in rows, in a semi-circle, and so on)
- The location and frequency of the students called on
On average, the right-handed teachers called on students as follows:
On left side of room: 3.17 times
In center of room: 1.69 times
On right side of room: 2.88 times
Note: Only one left-handed teacher was in the sample.
My hypothesis was that a right-handed teacher would pay attention to the left side of the room, so that he or she can pay attention to the class while writing on the board. The results proved that my hypothesis was correct.
A possible improvement in my project would be to include more left-handed teachers in the test.
